PLOW ATTACHMENT Filed July 10, 1956 Patented Mar. 9, 1937 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to a plow attachment, and more particularly to a slide or heel device attached to the standard of a plow.

An object of the invention is the construction of a simple and efiicient device for more easily operating a plow.

Another object of the invention is the construction of a novel device which is not only adjustable on the standard of a plow, but which can be quickly assembled and attached to the standard.

A still further object of the invention is the construction of a novel device that will run comparatively easy over the ground, which greatly reduces strain on the operator as well as the draft animal.

With the foregoing and other objects in view, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a View in side elevation of a device constructed in accordance With the present invention.

Figure 2 is a vertical sectional view, taken on line 2-2, Figure 1, and looking in the direction of the arrows.

Figure 3 is a fragmentary View, partly in vertical section and partly in side elevation, of the device shown applied to a plow standard, the device in this instance being placed in front of the standard, instead of in the rear as is shown in Figure 1.

Figure 4 is a perspective view of the device, with the detachable brace removed from the frame.

Figure 5 is a View in elevation, showing part in vertical section.

Figure 6 is an enlarged sectional view, taken on line 65, Figure 5, and looking in the direction of the arrows.

Figure 7 is a sectional view taken on line 1-1, Figure 5, and looking in the direction of the arrows.

Figure 8 is a fragmentary view, partly in elevation and partly in vertical section, of another embodiment of the present invention, while Figure 9 is a sectional view taken on line 99,

Figure 8, and looking in the direction of the arrows.

Referring to the embodiments illustrated in the accompanying drawing: attached to the plow beam l is metallic standard 2 which is provided with an elongated slot 3. Any desired style of 2. plowshare 4 may be assembled with the standard 2.

My heel device depicted in Figures 1 to 7 comprises a frame 5 which includes a runner or horizontal portion 6 and an upright, curved por- 5 tion 1. Near the outer end of horizontal portion 6 is a vertical aperture 8. A rearwardly-extending lip 9 is formed on the upright portion 1, by cutting out part of the upright portion to produce the elongated slot Ill. This lip 9 is some 10 what springy in action, to facilitate assembling and disassembling the detachable brace I I. The under face of lip 9 is provided with a groove pocket l2 (Fig. 5), which looks the flat head I3 of detachable brace ll normally in lip 9, thereby 15 making an excellent securing means. The lower pointed end ll, of brace l I, is normally seated in aperture 8. The outer end of pocket I2 is beveled (as will be clearly seen in Fig. 5) to allow the head l3 to be forced out of pocket l2 by the 20 operator; the movement of removing the brace is indicated by dotted lines A, A in Figure 5. It will therefore be seen that lip 9 will have a slight upward movement when manual strain is placed upon brace H, to remove it from the frame 5. 25

A bolt I5 is employed for attaching the device to standard 2; this bolt may be also used for attaching plowshare 4 to the standard. As seen in Figure l the device is applied at the rear of the standard 2, while in Figure 3 it is shown placed 30 in front of the standard 2, with lip 9 and part of brace ll extending into slot 3 of the standard.

In the embodiment shown in Figures 8 and 9 the rearwardly extending lip 9a has a groove pocket [2a formed by a struck-up portion I6. 35 The upper end of brace I la is securely held in the groove pocket 12a, but when the operator wishes to remove the brace from the frame this can be done similar to the manner of removing brace II, as hereinbefore described. 40

The device can be easily adjusted vertically on standard 2, to secure the desired depth which the operator wishes the furrow to be. Further the important brace II can be quickly assembled with frame 5, or detached therefrom, as well as 45 the device can be quickly applied or detached from plow standard 2 through the manipulation of bolt l5.

It is also to be noted that Figures 5 and 7 show part of head l3 of brace ll entirely sur- 50 rounded, as at IT, by a portion of lip 9; this constitutes what might be styled the closed end of the groove pocket l2, whereby a very secure assembling of the brace with the lip, against accidental displacement, is accomplished. 50

While I have described the preferred embodiments of my invention and illustrated the same in the accompanying drawing, minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a device of the class described, the combination of a frame comprising a horizontal portion and an upright portion, said upright portion provided with a rearwardly-extending lip, a brace frictionally held at its upper end in place against said lip, and means on said horizontal portion and the lower end of said brace securin same together.

2. In a device of the class described, the combination of a frame comprising a horizontal portion and an upright curved portion, said hori- Zontal portion provided near its outer end with a receiving aperture, said upright curved portion provided with an elongated slot and with a cutout lip extending rearwardly from said slot and integral with the upper portion of said curved portion, said lip being of a springy nature and provided on its under face with a pocket, said pocket having an outer beveled end and inner inclosing end, a detachable brace provided with a pointed lower end extending into said receiving aperture, a head formed upon the upper end of said brace, and said head positioned in said pocket and having part within the inclosing end 'of said pocket, substantially as shown and described.

3. In a device of the class described, the combination of a frame, a bodily-removable brace engaging at its ends parts of said frame, and means on said frame and on both ends of said brace frictionally holding the same together, whereby the brace can be entirely removed from the frame by knock-out blow thereon.

4. In a device of the class described, the combination of a frame comprising a horizontal and an upright portion, said upright portion provided with a rearwardly-extending lip, a detachable brace extending at its lower end into said horizontal portion, and the upper end of said brace and said lip provided with frictional locking means, whereby an outward push or blow upon the brace will result in the removal thereof of! said frame.

5. In a device of the class described, the combination of a frame provided witha horizontal portion and with an upright portion, said upright portion provided with a rearwardly-extending lip, a brace fixedly held at its lower end upon said horizontal portion, and means on said lip and the upper end of said brace frictionally holding the same together.

6. In a device of the class described, the combination of a frame provided with a bodily-removable detachable brace, socket means only holding one end of said brace fixedly in place, and means holding the other end of said brace frictionally in place, whereby this last-mentioned end can be quickly slid to a disengaging position and the entire brace bodily removed from said frame.
